I have a 2012 F350 6.7 automatic dually. I tuned the truck with SCT x4 canned street tune after I did the dpf delete. The truck ran great! A few months later I put an airaid intake and did an egr delete on it. After the egr delete it has not been running right. I returned it to stock and then tried both the canned street tune and tow tune on it. The transmission shifts hard and the truck lacks power. Does anyone have any insight on this? Does this tuner not support an EGR delete?
